A proximal basal chevron osteotomy was carried out on 20 patients (22 feet) with a Tailor's bunion deformity. The follow-up was of a minimum of 3 years for all patients. Direct surgery on the fifth metatarsophalangeal joint for bunionette treatment has often been unsuccessful and there have been recurrences due to metatarsophalangeal instability. Basal osteotomy is therefore preferred. The patients were satisfied. The intermetatarsal 4-5 angle was noticeably reduced. There were no postoperative complications and no recurrences. The fifth metatarsophalangeal joint was corrected despite the absence of direct surgery and remains stable. This operation is recommended for acute bunionettes with intractable plantar keratosis.
